Abstract

Recently available spectroscopic data have been used to derive new values for the enthalpies of formation at 298.15 K of gaseous ThO, ThO2, UO, UO2, UO3, and PuO, and PuO2. These new values of δHf0(298.15 K) are in good agreement with previously recommended values for UO, UO2, and PuO, but not for the other molecules. Inconsistencies among evaluated thermodynamic data have been resolved for ThO (g) and UO3 (g). Recommended values are derived for PuO2 (g) and ThO2 (g); however, additional experimental work on these molecules is needed.
